A rapid wet digestion method for plant analysis procedures to digest and prepare the samples. Calcination methods, using classical muffles furnaces, allow the treatment of a high number of samples but the process requires at least 24–48 hours.

Comparison of techniques for nitrogen analysis in potato cropsr infra-red reflectance (NIR) spectroscopy. Models to estimate [N] from NIR have been developed using either Kjeldahl or Dumas for calibration. Estimates of [N] from all three methods, are highly correlated. However, [N] measurements by Kjeldahl and Dumas are not in agreement. Kjeldahl has a recover作者: nonsensical 時間: 2025-3-23 02:48

Relationship between aboveground dry weight and N, P and K concentrations in grassland species: A guessary to determine the nutrient status of these two cations in permanent grasslands. Despite big differences in production, the equations of the nine grass species are very similar for all these nutrients (N, P, K and Mg). The parameters of these equations given here can be used as a guide to determine a satisfactory nutrition.作者: 我悲傷 時間: 2025-3-30 00:35
